HUB FOR BlCYCLE-WH EELS.

SPECIFICATION forming part of Letters Patent No. 614,334, dated November15, 1898.

\ Application filed April 16, 1897. Serial No. 632,381. (No model.)

To all whom it may concern.-

Be it known that I, CHARLEs E. MCGLIN- CHEY, a citizen of the UnitedStates, residing at Highlandville, Massachusetts, have invented certainnew and useful Improvements in I-Iubs for Bicycle-Wheels, of which thefol lowing is a specification.

The object of my invention is to provide a simple, economical, andefficient hub for a bicycle-wheel; and the invention consists in thefeatures, combinations, and details of construction hereinafterdescribed and claimed.

In the accompanying drawings, Figure 1 is an end elevation of a hubconstructed in accordance with my improvements and showing a portion ofthe tangential spokes arranged in dotted lines; Fig. 2, a longitudinalsectional view taken on line 2 of Fig. 1, and Fig. 3 an elevation of oneof the spoke-flange thimbles removed from the cylinder which forms thehub.

In the art to which this invention relates it is well known the mostefficient wheels are made by arranging the spokes in tangential linesfrom the points at which they engage the hub and are connected with therim, so that the pull is transmitted in as straight a line as possible.

' The primary object of my invention, therefore, is to provide a hubthat will permit of such engagements and connections with the hub andrim, which will more fully appear from the following description and aninspection of the drawings.

In constructing a hub in accordance with my improvements I use a centralcylindrical tube A of the desired size and shape and provide it withthimbles B B, one at each end of the cylindrical portion. These thimblesare provided with what I term spoke-flanges B secured at their innerlateral edges and which preferably form a portion of the thimble, thewhole being made or stamped from sheet metal, which gives the greateststrength with the least amount of material.

In order to provide for the connections of the spoke in an economicaland efficient manner, I make a number of cylindrical tangentialportions 1) b, one setof which is arranged on one side of the flange andthe other on the other side of the flange and alternating from side toside. These cylindrical projections are made by cutting the peripheraledge of the flange into any desired number of reot-angular projectionsand then rolling or bend ing the same over, as is shown fully in Fig. 2,so as to form the cylindrical pockets for the reception of the heads ofthe spokes C.

The thimbles may be secured to the cylin-' drical portion in any desiredmanner, preferably by brazing, and the flanges, instead of being made ofthimble-shaped portions, may be simple flanges secured directly to thecentral tube in any desired manner. The advantages due to the use of myimprovements are that the hub may be formed quickly and economically,and the cylindrical projections being arranged at right angles to radiallines form bearing portions for the spokes and secure the same in a truetangential manner. I claim 1. In a hub for bicycle-wheels, thecombination of a central tubular portion, a spoke= flange formed ofsheet metal having its outer peripheral edge out into a number ofprojections such projections being alternately bent to one side and theother of the flange so as to form cylindrical tubular spoke -pockets andarranged at substantially a right angle to radial lines, substantiallyas described.

2. In a hub for bicycle-wheels, the combination of a central tubularportion, thimble portions arranged thereon one near each end of thecentral tubular portion, and a lateral flange on each of such thimbleportions formed of sheet metal integral with the thimble portion andhaving their outer peripheral edges cut so as to form projections andbent alternately to one side and the other of the flange so as to formcylindrical tubular spokepockets at right angles to radial lines,substantially as described.
